Application mamey 2, 1921. serial No.` 4ssen of that type which are provided with means for cooling' the water before itis delivered from the bubbler. t t

)nefeature `of the present invention relates to a novel bubbling' fountain by which the cold waste water which 'is discharged yfrom the bubbler may befused to pre-cool the supply water before it is deliveredto -the cooling meansl In bubbling'fountainsof this type there is always'a certain amount of water discharged from the bubbler which 1s not used and in 'the' case of 'ice-cooled bubbling fountains such waste water is at a considerablylower temperature than the water supplied to the cooling` means; My invention contemplates the provision of means whereby Isuch waste water may be used to, decrease thetemperature of, or pre-cool, the supply water before it is delivered` to the cooling means. An advantage which results from this construction is that considerably less ice will `be re'- quircd to cool the water than. is required where no pre-cooling: takes place.

` In order to give anv understandingof my inveition I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed outvin the appended claims.

In the drawings I have shown at 1 a bubbler of any suitable or usual construetion to which the water is supplied through a pipe Q, the latter having a valve 3 therein by which the water may be turned on or shut olf. i

is a fragmentarysectional view closed bythe cover 6J y y y Vith this construction the `water will` be pipe to the rpre- The type of bubbling fountain herein Illustrated is the ice-cooled `type audit cornprises acoolingg,` coil l which 'receiveswater from a suitable source `of supply and delivers `it to the valved vconnection 2 leading' to the bubbler l( This cooler 4- is shown as encircling;l a tank 5 in which ice may he placed, said tank having the removable cover Gthrough which the ice may be delivered thereto `The, cooling' coil 4 is shown closelyencircling the tank 5 and' as enclosed in a suitable heat insulating casing to prevent a loss of heat by radiation. heat insulating casing herein shown comprises two concentric shells 7 and 8 which encircle the cooling;l coil 4 and 'which are The spaced apart, the space between themy beingy filled with some insulatingr4 material 9. These concentric shells 7 and 8 are shown as secured attheir lower endsf to a lower head IOv and at their upper ends to' an upper head 110, said head having the opening therein leading to the tankr 5` and which is cooled 'as it passes through the cboling coil l so that `the water which 1s deliveredfrom the bubbler will always be Aice-cooled water'.

"The parts thus far described are, orinay be, all as usual in ice-corded bubblingv 'fountainsainl formino part of my presentA inven tion."` i In accordalufe'with the present invention Ihave provided means whereby Athe waste water which is discharged from the bubbler l may be utilized topre-coolithe water which isldelivered to the coolingcoil Ll and in the preferred embodiment'of my invention I accomplish this byy providing a pre-cooling coil which is connected to the water supply and which is also connected to thecooling coil 4 so that the water supplied 'to the bubbler will lpass through the pre-cooling` coil before :it is delivered to the cooling coil. T he prefcooling coil is arranged to be cooled by the' waste water delivered from 'the bubbler l and this can conveniently be done by placing said cooling coil in a chamber to which such waste water is delivered, said chamber preferably having a suitable over# flow leading tothe drain. WV ith such an arrangement it is possible to reduce the temperature of the water several degrees before it is delivered to the cooling coil land therefore the work which the ice has to do in cooling the water forl the vbubbler is greatly reduced thus effecting a considerable saving in the quantity of. ice required.

- In the construction herein illustrated-the pre-cooling coil is indicated at 11 and it is connected at its upper end to the lower end of the cooling coil 5 through a suitable conneet-ion 12. The lower end of the pre-cooling coil connects to the water supply through a supply pipe 13. This pre-cooling coil is shown as arranged in a chamber 14 constructed to receive the waste water def livered from the btibbler 1. i

There are` various vconstructions which maybe adopted to provide for such a chamber to contain the pre-coolingcoil and receive the lwaste water. struction is illustrated in. Fig. 1 whereinthe chamber 14 is situated beneath the ice tank 5 and within the same Casing as that` which i contains the ice tank andcooling coil. The

casing `including` the concentric shells 7 and 8 with their intermediate insulation l9 is extended below the ice tank 5 and cooling coil 4to providesutlicient room for the prej pipe 17 which extends down between the .with the drain.

cooling coil 11 and the chamber 14. `This chamber is `herein shown as an annular chamber formed between the lower end of the V`shell 7 and ak cylindrical member` 15I situated beneath the ice tank.y The bottom of the chamber 14 istormed by aplate 16 extending acrossthe shell 7 and supported onthe lowe-rhead 10. 4 I

The bubbler 1 is provided with 'a waste shells 7 and 8- and is'th'erelore surrounded bythe insulating material 9. This `waste pipe 17 leads to a connection 18 that extends up through the head 10 and plate 16 and communicates with the v"chamber 14. The chamber 14 is provided with an overflow pipe 19v whic-h extends through the `bottom thereof and is connected'ctothe d'rain by means ot' a vconnection v20. Thisconnection 20 leads vint-or the ehamber22 formed in the base 21 on whichvthe tountaincis supported and the chamber 22 is` connected by a vpipe The upper end of the overflowV pipe 19 issituated adjacent ,the` top Ot the chamber 14 and. vas `a result the `chamber 14 willbe always lilled with the as a result t-hel'water in the` prefcooling coil Y 11 will have its temperature considerably reducedbe't'ore it is delivered to thef cooling coil 4. It will, therefore, require less ice to cool the water in the coolingcoil 4 and the `device illustrated therefore acts as an A desirable con..

ice economizer. i The waste pipe 17 is shown as having a connection 24 leading directly t0 the chamber 22, said connection being c-ontrolled by a valve 25. This connection 24 constitutes a drain connection by which the chamber 14 and drain `pipe 17 may be drained. f

26 indicates a drain pipe connected to the bottom of the ice tank 5 and leading throughl the lower head 10 into the chamber 22, said drain pipe being provided with a suitable valve 27. `This drain pipe is for the purpose of draining the'water from the ice tank 5,. The stand 21 is formed with an opening 28through which the valve 27 is accessible. t y i 29 indicates an air chamber. connected to the pipe connection 2 for the purpose of preventing water hammer in case the valve 3, is suddenly closed.l
